Description

Large-Capacity Coin Hopper

The present invention relates to a hopper device for forcibly sending coins in loose conditions. More specifically, the present invention relates to a hopper device for a small disk body that can send out medals and tokens used for game machines one by one. More specifically, the present invention relates to a large capacity coin hopper suitable for a game device using many medals and tokens.

As used herein, the term "disc body" includes, of course, disc-type coins used as money. In addition, the term "coin" as used herein includes not only money, but also medals and tokens used in the game.

To date, a variety of hopper devices for disc bodies have been developed. For example, Japanese Patent Application No. 59-022825 by the present applicant discloses a coin delivery device which is a disc body. Japanese Patent Application No. 59-022825 has been published as Japanese Patent Publication No. 62-45588. In addition, Japanese Patent Application No. 59-022825 has been patented in the United States as Patent No. 4,589,433.

17 is an overall perspective view schematically showing the coin dispensing apparatus. In the apparatus, a circular base plate 302 is provided which is inclined with respect to the horizontal plane. The base plate 302 is provided with a tank 305 for storing coins for delivery. The tank 305 is provided with a rotating disk 306. The disk 306 is rotated about the axis of rotation in an inclined state upright with respect to the horizontal plane. The rotating disk 306 has a disk-shaped support 309 on the central upper surface.

The rotating disk 306 also has a plurality of pins 308 for supplying coins, which are arranged in the outer circumferential portion 306a in the circumferential direction at regular intervals. The device also has a plurality of balls (not shown) for bearings, which are inserted between the outer circumference 306a of the rotating disk 306 and the base plate 302. These balls constitute a bearing device that freely supports the outer circumferential portion 306a of the rotating disk 306 on the base plate 302. The device also has an outlet knife 310 whose tip meets the upper portion of the outer circumferential edge 309a of the base 309. The exit knife 310 receives coins on the upper edge 310 and sends them to the exit chute 311.

Moreover, the apparatus 315 which stirs the coin in the hopper 305 is arrange | positioned in the center of the support part 309. As shown in FIG. Also, on the upper portion of the exit knife 310, rollers 313 are located oppositely. That is, the roller 313 is equipped with a rotating free path on the hinged inverted U-shaped movable arm 312. The movable arm 312 is for example energized by a spring of a switch (not shown) for counting coins. Thus, when the coin passes through the outlet at the upper part, counting of the coin C is performed.

In other words, the switch for coin counting is activated by the fact that the passing coin C pushes the roller 313 against the spring (not shown). Also, the elliptical portion 314 shown in the upper portion of FIG. 17 is a wiper. The wiper 314 prevents the coin C from being sent to the upper outlet 307 in the overlapped condition. Reference numeral 317 denotes a spring plate. The plate 317 is used to press the wiper 314 on the circumferential wall around the rotating disk 306 or hood 319. Further, reference numeral 301 shown in the bottom part of FIG. 17 is a frame for mounting. The frame is used to mount the device via a base B, to a variable desired position, medal change device, or the like.

Further, in the coin processing unit, a support 309 proportional to the size of the coin C is provided in the center of the rotating disk 306. In addition, a plurality of coin supply pins 308 protrude on the circumference of the rotating disk 306. Thus, a pocket for the coin C is created between the base 309 and the pin 308. Thus, when the rotating disk 306 is rotated in the hopper 305, the coins C in the hopper 305 are withdrawn one in each pocket. The coins C taken out one by one are sent to the upper outlet 307, and the coins C are sent out to the outlet chute 311 via the outlet knife 310.

However, since the coin, which is a small disk body, is continuously sent at a high speed, the hopper device has a problem. That is, since the capacity of the high speed coin dispenser is relatively small, there is a problem that coin dispensing is terminated immediately. In particular, in a game machine that uses a large amount of medals, there is a problem that a medal shortage occurs during the game and loses interest in the game.

Among various things that have been developed as a hopper device for a disc body to date, for example, a coin dispensing device is shown in Japanese Patent Publication No. Hei 6-44305 (Japanese Patent Application No. Hei 2-152852) by the present applicant. . Further, Japanese Patent Publication No. Hei 6-44305 (Japanese Patent Application Hei 2-152852) has been patented in the United States (US Patent No. 5,122,094).

18 illustrates an overall perspective view of the coin dispensing apparatus. In this arrangement, the base plate 404 is provided inclined upright with respect to the support frame 403. A tank 401 for storing coins C is installed on the base plate 404. In addition, a coin outlet 460 is installed in the tank 401. The coin supply disk 450 is freely installed in the tank 401. That is, the coin supply disk 450 in the tank 401 is installed on the shaft 442 of the motor. The disk 450 is formed into a deep plate shape having a thick bottom and a circumferential wall integrally. At the bottom, several coin receiving holes 452 through which coins can enter are provided and spaced apart in the circumferential direction.

Thus, around the axis 442 upon rotation of the motor, the disc 450 is rotated clockwise as shown by arrow A in the tank. When the disc 450 is rotated, the coin in the tank 401 is stirred and the coin enters the hole 452 for accepting the coin. Further, on the bottom surface of the disc 450, a long nail 453 for coin supply protrudes between the coin receiving holes 452 (see FIG. 19). The supply nail 453 is inclined in detail with respect to the radius of the disc 450. That is, the supply nail 453 extends from the outer circumference line of the disc 450 to the hole 452. Further, the protrusion of the supply nail 453 is slightly larger than the coin thickness.

A support base 454 concentric with the output shaft 442 protrudes on the base plate 404. The height of the support base 454 is manufactured to be finer than the thickness of the delivery coin. The disc 450 is freely rotated on the support base 454. Thus, coins fall one by one between each supply nail 453 on the bottom surface of the disc 450. That is, coins fall one by one from the hole 452 to a position between each supply nail 453. Thus, the coins are supported on the base plate 404. In addition, on the base plate 404, an elliptical coin guide plate 455 is loosely coupled around the circumferential direction of the support base 454. The guide part 456 for the coin exit is provided in the guide plate 455. Coin outlet 460 is also formed in tank 401 located in the circumferential direction of disk 450. That is, the coin outlet 460 is provided downstream from the outlet guide 456 of the guide plate 455. Thus, by the supply nail 453, the coins are guided along the elliptical guide plate 455 in the clockwise direction of the arrow A. That is, coins are guided from the outlet guide 456 to the outlet 460 by the supply nail 453. Downstream of the coin outlet 460, the fixed guide roller 461 is provided freely for rotation. That is, the fixed guide roller 461 is attached to the shaft 462. In the upper part of the coin outlet 460, the movable guide roller 463 which cooperates with the guide roller 461 is provided. That is, the movable guide roller 463 is freely installed on the shaft 464. In addition, the shaft 464 of the movable guide roller is provided with a rotational freedom path on the swingable actuator 466. In addition, the shaft 464 of the guide roller 463 penetrates into the base plate 404 and penetrates through the arc-shaped groove 465 formed in the base plate 404. The actuator 466 is provided with a rotational freedom path on the bracket 467 provided on the lower side of the base plate 404. That is, the actuator 466 is installed on the shaft 468 of the bracket 467 and is held by a spring (not shown). In addition, a count sensor (not shown) operated by the actuator 466 is installed on the bracket 467. The actuator 466 is pushed and moved through the movable guide roller 463 by a coin passing through the outlet 460. The coin is sent out from the outlet 460 while being guided by the fixed guide roller 461 and the movable guide roller 463. At this time, the movable guide roller 463 is pushed and moved by the coin passing. In addition, the linked actuator 466 operates the sensor and counts the coins issued.

However, the hopper device has a problem because it continuously delivers coins at high speed. The conventional coin dispensing device is high speed, but the tank capacity is small. Therefore, there has been a problem that coin delivery is terminated quickly. In particular, when using a game machine using a large number of medals, there is a problem that a medal shortage occurs. That is, there was a problem that a medal shortage occurs in the medal game machine and the medal shortage damages the interest of the game.

The present invention was devised to solve the above problems, and the present invention was devised to greatly improve the capacity of the disc body in a disc body dispensing apparatus such as a coin or medal. That is, the present invention has been devised for the purpose of significantly reducing the frequency of disc body supply in a disc body hopper device such as a coin or token.

The present invention provides a large-capacity coin hopper, wherein the hopper includes a main coin tank means and a coin dispensing means formed in a tubular shape, wherein the main tank means is positioned at an inclined axis thereof, and a coin outlet is formed therein. The coin dispensing means is inclined to stand upright and freely rotates in the main tank means, and the hopper is formed so as to communicate with the case means and a case means communicated with the main tank means, and formed in a large jar shape.

In addition, the present invention provides a large-capacity coin hopper, characterized in that the conveyor means is a belt conveyor.

The present invention also provides a large capacity coin hopper, characterized in that the conveyor means is a chain conveyor.

Another object of the present invention is to provide a delivery device with a greatly improved capacity while suppressing the height of the entire delivery device. That is, an object of the present invention is to significantly reduce the frequency of supply of a disc body in a delivery device for coins or tokens.

The present invention provides a first tank means for storing a coin, which is formed in a tube shape, the axis of which is inclined, and has a coin outlet, a coin dispensing means in which a rotating free passage is arranged and inclined upright in the first tank means, and the coin dispensing means.

1 to 8 show one embodiment according to the invention and FIGS. 9 to 16 show another embodiment.

First, an embodiment according to the present invention will be described with reference to FIGS. 1 to 8.

1 is a perspective view schematically showing an embodiment according to the present invention. Reference numeral 131 shown at the lower right in FIG. 1 is a rectangular bed plate. The bed plate 131 is horizontally installed, for example, is installed in a game cabin using coins or the like. Also, two substantially triangular dimensional frames 132 are upright and fixed to the left and right edges of the bed plate 131, respectively. On both dimension frames 132, a generally rounded base plate 133 is held upright and slightly inclined.

2 is a side view as seen from the side of FIG. In FIG. 2, on the outer circumferential portion of the base plate 133, a hood 134 which is generally annular is fixed. Further, in the hood 134, the coin carrying rotating disk 135 is stored freely in rotation. In addition, on the annular hood 134, the tubular tank 136 is provided roughly. Since the configuration is almost the same as the prior art shown in Fig. 17, more detailed description is omitted.

The base plate 302 in FIG. 17 corresponds to the base plate 133 here. Also, the hood 319 in FIG. 17 corresponds to the hood 134 here. In addition, the rotating disk 306 in FIG. 17 corresponds here to the rotating disk 135. In addition, the tank 305 in FIG. 17 corresponds here to the tank 136. In addition, the support part 309 in FIG. 17 corresponds to the support part 137 here (refer FIG. 6). Also, pin 308 in FIG. 17 corresponds to pin 127 here (see FIG. 6). Further, the stirling device 315 in FIG. 17 corresponds to the stirling device 139 here (see FIG. 3). In addition, the outlet chute 311 in FIG. 17 corresponds to the outlet chute 141. In addition, arm 312 with roller 313 in FIG. 17 corresponds to arm 129.

The large shallow box shape shown in FIG. 6 is a case 151 for storing the device. The case 151 is made of a resin molding or a metal molding. A semicircular opening 152 is formed in the upper portion of the bottom of the case 151. On the bottom rear surface of the case 151, the mounting pipe part 153 which slightly surrounds the opening 152 protrudes (refer FIG. 2).

As shown in FIG. 2, the pipe portion 153 is inserted into the tank 136 and fixed by screws 154. That is, the case 151 is fixed to the tank 136 via the pipe part 153. On the bottom surface of the case 151, a rail 155 largely enclosing the opening 152 is formed in a roughly circular annular shape (see FIG. 6). The rail 155 is for guiding the belt conveyor device 161 which will be described later (see FIG. 4). The small circular box portion 156 is formed at the lower right side of the large box case 151.

In the box portion 156, an electric motor 162 is stored from the outside thereof and fixed by screws (not shown). In addition, the drive shaft of the electric motor 162 protrudes freely in the case 151. Gear 163 is fixed to the protruding drive shaft. In addition, a gear 164 that cooperates with the gear 163 is hinged to the box portion 156 (see FIG. 4). The mounting nut part 157 is formed in each corner of the case 151, respectively. In addition, a pair of legs 159 protrude from the bottom of the case 151.

The large deep angled jar-like member shown in FIG. 1 is a tank 171 for storing a large amount of coins. The second large tank 171 is made of resin molding or metal molding. In the bottom rounded wall of the tank 171, an approximately rectangular opening 172 is formed. In addition, the mounting plate portion 173 is formed to protrude from the round wall forming the opening 172. The plate portion 173 and the rounded wall forming the opening 172 become the lid plate of the case 151. The one round wall and the plate portion 173 are fixed to the case 151 by the screw 174 via the nut portion 157 (see FIG. 1). That is, the tank 171 is fixed to the case 151 via the round wall and the plate portion. A rail 175 largely enclosing the opening 172 of the tank 171 is formed in the shape of a generally circular ring on the back of one round wall (see dashed line in FIG. 1).

The rail 175 is paired with the rail 155 of the case 151 described above. The paired rails 155 and 175 are for guiding the belt conveyor device 161. The caterpillar type belt conveyor device 161 is made of resin molding or an object formed of metal. 8 is an enlarged perspective view showing the main part of FIG. In FIG. 8, a portion of the conveyor apparatus 161 is shown enlarged. The belt conveyor apparatus 161 is an endless belt formed by hinge 160 of a plurality of small rectangular plates 169, respectively. In the back portion of the rectangular plate 169, a rack 167 that cooperates with the gear 164 is formed. In addition, protruding plates 166 are formed on the surface portions of various plates 169 among many rectangular plates 169.

In the belt conveyor apparatus 161, one end of each hinge shaft 160 slides freely into the rail 155 of the case 151, as shown in FIG. In addition, a large hopper 171 is provided as a lid of the case 151. At this time, the other end of each of the hinge shaft 160 of the belt conveyor device 161 is slide freely inserted into the rail 175 (see Fig. 1). Accordingly, the belt conveyor apparatus 161 is slid freely arranged between the rails 155 and 175.

(Example 1)

In this embodiment consisting of the above configuration, a large amount of coins (not shown) are put in the second large tank 171 and stored in a loose state.

Thus, some of the large amount of coins flow from the openings 172, 152 to the main tank 136. In addition, some of the many coins inserted into the second tank are stored up to the height of the opening 152. Thus, when the electric motor (not shown) of the rotating disk 135 is driven, the rotating disk 135 is rotated counterclockwise. As a result, coins in the main tank 136 are picked up one by one by each pocket of the rotating disk 135. In addition, as described above, the coin holding pocket is created by the pin 127 and the support 137 projecting on the surface of the rotating disk 135.

The coins picked up one by one are sent to the top and sent to the exit chute 141 via an exit knife (not shown). As described above, coins in the main tank 134 are discharged from the outlet chute 141. On the other hand, in the second large tank 171, many coins remain until the height of the opening 152 is reached. The amount of coins in the main tank 136 and the load of the rotating disk 135 are reduced. At this time, for example, by detecting a decrease in load by a sensor such as a current, the electric motor 162 is driven. Thus, the belt conveyor device 161 is rotated counterclockwise, for example. By scraping off by the plurality of protruding plates 166, the coins remaining in the second tank 171 are conveyed into the opening 152. Coins carried in the opening 152 fall into the main tank 136. In this case, since coins are added in the main tank 136, coin delivery by the rotating disk 135 is continued without stopping. In addition, after the electric motor 162 is driven, for example, the electric motor 162 may be stopped at a predetermined time. Moreover, in the practical example, although the conveyor apparatus 161 is manufactured by the caterpillar type belt conveyor, other belt conveyors may be used.

For example, endless rubber belts, leather belts or improved woven belts may be used. It is also preferable that the guide rail of the belt is widely used. It is also possible to use improved endless metal belts or plastic belts or chain belts. In addition, although omitted in the description, the above-described conveyor apparatus 161 may be made of a chain conveyor. In this case, a sprocket may be used instead of the gears 163 and 164. In addition, although omitted in the description, the conveyor apparatus 161 described above may be manufactured as a bucket conveyor.

In this case, the coin may fall by flipping each bucket to the upper position. Further, although the coin scraping means of the belt type conveyor apparatus 161 is made of the protruding plate 166, other forms may be used. For example, a spoon or small jar may be used instead of the protruding plate 166. In addition, the sizes and positions of the openings 172 and 152 may be optimally selected in consideration of the conveyor apparatus 161. That is, the size and position of each opening 172, 152 may be determined by considering the fall direction of the coin by the conveyor apparatus 161, etc.

In addition, although the rotating disk 135 having the supporting portion 137 and the pin 127 has been described, it is also possible to use a rotating disk (not shown) having a hole for accepting coins.

Next, another embodiment according to the present invention will be described with reference to FIGS. 9 to 16.

9 is a schematic perspective view of another embodiment according to the present invention as viewed obliquely from above, FIG. 10 is a side view of FIG. 9 viewed from the left, FIG. 11 is a rear view of FIG. 10 viewed from the left, and FIG. 13 is an enlarged cross-sectional view showing a part of the driving means shown, FIG. 13 is a perspective view from which the main part of FIG. 9 is deleted, FIG. 14 is a perspective view from which a part of the main part of FIG. 9 is deleted, and FIG. It is sectional drawing, and FIG. 16 is an exploded perspective view which shows the principal part of FIG.

In the second large tank 202, a large amount of coins are introduced from the inlet 205 and stored in a loose state. Therefore, some of the large amount of coins flow from the prismatic case 210 to the first tank 201. The first clutch 247 is mounted to the output shaft 242 for the drive disk 250. The gear case 241 also has an output shaft 242. The second clutch 248 is also mounted to the output shaft 243 for the drive belt 214 for carrying coins. The case 210 also has a coin carrier belt 214.

For the coin dispensing operation, the coin supply disk 250 is rotated in the first tank 201 clockwise when the motor 240 is rotated in both directions, under the operation of the first clutch 247. The coin carrier belt 214 in the case 210 stops under the operation of the second clutch 248 at this time. As a result, the coin in the tank 201 is stirred by the protrusion on the disk 250 and enters the receiving hole 252 of the disk 250. The received coin passes through the hole 252 and is supported on the base plate 204. Coins are then sent by the nail 253 in the direction of arrow A, which protrudes from the bottom of the disk 250. Thus, coins are sent along the guide plate 255. Thus, the coin pushed and moved by the nail 253 is directed towards the exit 260. That is, the coin is guided by the exit guide 256 of the plate 255 for the exit 260.

The coin is sent out from the outlet 260 by the outlet guide 256, the fixed guide roller 261, and the movable guide roller 263. At this time, the movable guide roller 263 is pushed by a coin. Thus, actuator 266 activates a sensor (not shown), which counts the delivery coins. As described above, coins in the first tank 201 are sent out. On the other hand, many coins remain in the second tank 202. At this time, when it is determined that the amount of coins in the first tank 201 is small by the current change of the motor 240, the motor 240 is reversely rotated. Alternatively, when it is determined that the amount of coins in the first tank 201 is reduced by the residual flow rate sensor (not shown), the motor 240 rotates in reverse.

As a result, the rotation of the coin supply disk 250 in the first tank 201 is stopped by the operation of the first clutch 247. Then, the power of the motor 240 is transmitted to the belt 214 in the case 210 by the operation of the second clutch 248. The belt 214 is rotated counterclockwise, for example. Thus, the coins remaining in the second tank 202 are scraped off by the plurality of protrusions 215 of the belt 214. The scraped coins slide over the curved wall 209 and are transported from the opening 213 to the first tank 201. In this way, the coins in the first tank 201 are replenished. Alternatively, the coin in the first tank 201 is supplied for a predetermined time. In addition, the motor 240 is stopped to stop the coin supply, at this time there is no coin delivery. In addition, the motor 240 is rotated in both directions, at this time there is a coin delivery.

(Example 2)

Referring to the accompanying drawings, a second embodiment according to the present invention will be described.

A cylindrical first tank 201 for coin storage is installed on the base plate 204 which is supported inclined and standing upright next to the support frame 203 (see FIG. 13). By fixing to the first tank 201, a large rectangular cylindrical case 210 is provided (see FIG. 14). The bottom of the case 210 is provided to be lower than the bottom of the first tank 201 (see FIG. 9). In addition, a second tank having a large jar shape is provided in the case 210. The case 210 and the second tank 202 are secured to the base 204 by bolts 211 via six long legs 212 (see FIG. 10). The first tank 201 and the case 210 and the second tank 202 are communicated with each other, and can store a large amount of coins. In the first tank 201, a coin discharging disk 250 formed in a deep plate shape is mounted with a rotating free path (see FIG. 13). Also, a coin carrier belt 214 is provided on the inner wall of the case 210 (see FIG. 14).

It is of course also preferable to use any member that can hold the belt 214 and that can be installed freely on the slide.

The coin carrier belt 214 is an endless belt made of rubber, leather or cloth. On the surface except for each end of the belt 214, projections 215 for carrying coins are spaced apart. In addition, the distance between the protrusions 215 is of course determined by considering the diameter of the coin. The width of the belt 214 and the protrusion 215 is preferably larger than the diameter of one coin. Also, endless belt 214 was used in the practical example. However, of course, a belt having a caterpillar shape made of a resin or a metal molded product may be used. When the coin mailing belt 214 is driven, the coins stored in the case 210 in communication with the second tank are raised. The coins are then sent from the opening 213 to the first tank by the slide curved wall 209 formed in the case 210 (see FIG. 14).

The second tank 202 is formed into a large jar shape having a large inlet 205 for coin input. Coins injected from the inlet 205 are stored abundantly (see FIG. 9). That is, a large amount of coins introduced from the inlet 205 of the second tank 202 is stored in the case 210 in a loose state in the second tank 202. When the motor 240 is reversed, the belt 214 on the inner wall of the case 210 is rotated under the operation of the second clutch 248. Rotating belt 214 raises the coins stored by protrusion 215. The raised coins slide over the curved wall 209 and are transported from the opening 213 into the first tank 201. In addition, coins in the first tank 201 are carried by the disk 250.

In this practical embodiment, one motor and first and second clutches were used. However, of course, similar effects can be obtained by using two motors. In addition, in the present practical embodiment, a disc having holes for accommodating coins has been described. However, it is of course also preferable to use a rotating disk (not shown) having a base and a pin.

The present invention configured as described above adds a second tank to the main tank, and the conveyor means from the second tank to the main tank are arranged. Thereby, a large amount of coins can be included in the main tank and the second tank to communicate with. In addition, since the coins remaining in the second tank can be transferred by the conveyor means, the effect that all large-capacity coins can be used is obtained. Therefore, a great advantage is obtained that game interest can be maintained without running out of coins, especially in game machines using a large amount of coins.

In the present invention described above, a second tank for coins is added to the main tank, and coin conveyor means for conveying coins from the second tank to the main tank is arranged. As a result, the main tank and the second tank communicated with each other can suppress the height of the entire delivery device and can store a large amount of coins. In addition, the coins remaining at the bottom of the second tank can be transported to the main tank by the conveyor means, and can have a significant effect that the use of all large amounts of coins can be obtained. Therefore, in particular, in a game machine using a large amount of coins, a remarkable effect can be obtained that the coin supply frequency can be significantly reduced.
